SPECIFICATION forming part of Letters Patent. No. 391,474, dated October23, 1888.

Application filed August 3, 1886. Serial No. 209,865. (NomodcL) To allwhom it may concern.-

Be it known that I, HENRY B. KEIPER, a citizen of the United States,residing at Lancaster, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements inTuyere-Irons; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The object of this invention is do away with the necessity for bends andelbows in the pipes connecting tuyere-irons with fans which furnish theblast.

To this end my invention chiefly consists in the combination of anaxially niovable tuyereiron body and nozzle attached thereto,with afixed cap or cover for said body, and clamping devices which secure themtogether but allow the axial adjustment of said body, so as topresentthe nozzle to the connecting-pipeat any convenient direction. Myinvent-ion further consists in certain additional features and detailsofconstruction,hereinafter particularly set forth and claimed.

Figure 1 represents aplan view ofthe tuyereiron embodying my invention.Fig. 2 represents a similar view of the body of said iron, the cover anddraft-regulator having been removed. Fig. 3 represents a verticalsection through the center of the complete tuyere-iron across thedraft-regulator. Fig. 4 represents a perspective view of the tuyere-irontaken from below; Fig. 5, a detail view of the draftregulator, and Fig.6 a detail view of the cinder-slide for the bottom of the tuyere-ironbody.

A designates the cap, which covers the top of the tuyere-iron body B,the latter being provided immediately below said cap with horizontalflanges or ears I), having in them slots 1), which follow the curve ofthe periphery of said body. Bolts (4. pass down through cap A and saidslots, holding said cap and body together, but allowing the body to beturned so as to present the inductionnozzle O in any one of a number ofdifferent directions. This nozzle extends radially outward from the sideof said body. When turned in the position desired, the body B and nozzle0 are locked therein by tightening said bolts.

D designates a shaft, which extends transversely across the top of saidbody B and turns in bearings A of cap or cover A. It has adraft-regulator, d, fast upon it, this regulator being approximatelytriangular in cross-section and turning with said shaft under a cen tralopening, A, of said cap. When one of the equal sides of the triangle isturned uppermost, the draft is out off. When one of the interveningapices of the triangle is uppermost, the draft is at its maximum.

A rod, E, extends transversely through the lower part of B, the body,and is provided at its ends with handles 2. To one of these handles acinder-slide, F, is rigidly secured, extending under the bottom of thebody Bin a plane parallel to said rod and fitting tightly against saidbody when in position to close the same. By pulling one of said handlesor pushin g the other said slide may be removed laterally from thebottom of the body,allowing cinders to fall from Within it. The reversemotion of course returns said cinder-slide to its normal position.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

In a tuyere iron, a fixed cap, in combination with a body having curvedslotted flanges, bolts passing through said slots and connecting saidbody to said cap, and a nozzle extending from the side of said body andmovable therewith, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY B. KEIPER.
